Method, and the way of distillation is more suitable for large-scale plant.The way of distillation being used widely at present mainly have multiple-effect evaporation, multistage flash distillation,
Press three kinds of desalination technologies of steam distillation.Since way of distillation desalination is a phase transition process, fresh water purity is high, can meet various use
The water quality requirement on way, but energy consumption is relatively high.But with intercoupling using a variety of method for desalting seawater and integrated technology
Development, the especially coupling technique of pressure steam distillation method and other method for desalting seawater with unique advantage so that the way of distillation is de-
The cost of salt is continuously decreasing, and competitiveness is full of in following market, therefore multi-method coupling desalination technology is in recent years

Because the way of distillation is for mass producing, the concentrated seawater quantity of discharge is very big, will just cause part after the long period
The significant change of sea area ocean temperature and concentration influences the growth of marine organisms, seriously destroys the marine eco-environment.It will be from basic
It is upper thoroughly to solve pollution problem caused by concentrated seawater discharges, the technological development for how realizing wastewater zero discharge should be conceived to.Distillation
There is multiple-effect evaporation technology higher cocnentration factor, the waste water of discharge to be easiest to realize zero-emission skill after secondary concentration in method
Art.But the technological process of current desalting seawater through multi-effect evaporation is using the higher concurrent of the thermal efficiency, in which if
The heat transfer coefficient of several effects below will be influenced if low temperature concentrated seawater viscosity is larger, therefore multiple-effect evaporation technology cocnentration factor is further
Raising is very restricted.In addition, the low temperature concentrated seawater discharged in concurrent carries out, second-compressed is more complicated, and hot method is
Stream of hot air is introduced from the external world and carries out spray evaporation to realize secondary concentration, but the damp-heat air formed after evaporating not only volume
Too big, and heat transfer coefficient is relatively low, condensation effect is poor, in addition must could most by moisture trap after damp-heat air condensation
Fresh water is obtained eventually, therefore entire technical process is relatively complicated.And in Chemical Manufacture frequently with reflux type, largely
On the shortcomings that overcoming concurrent, higher cocnentration factor can be obtained, the high temperature concentrated seawater at the same time discharged is easier to realize
Secondary concentration.But in reflux type feed liquid forward one effect be sent into when, can be only achieved boiling by one section of warm, because
This evaporation effect is poor, since for Seawater Desalination Project primarily to obtaining fresh water, institute is light in seawater in a counter-current configuration at this stage
Relevant application is not obtained in change.
